PSA: You can safely refer to those long "commit-ish" identifiers using just the first 7 or 8 chars (eg `88113a64`) without real risk of collision. Let alone in examples / gists!
Git will even warn you if the hash prefix you provide is ambiguous!
I had a collision the other day on a mediums-sized when using a 6 character hash and was surprised. Git let me know and told me which objects collided.
Wow, that's super unlikely. How many commits did the repo have?
According to [1] using 3 letters you'd need at least 72 commits to have at least 50% chance to observe a clash. Using 6 letters you'd need at least 3977 commits, lol.
